The source of the tropospheric ozone The tropospheric ozone has two major sources. One is intrusion from the stratosphere. Most of ozone in the atmosphere is in the stratosphere and created from solar UV radiation. The stratospheric ozone sometimes flows into the troposphere by the upper layer trough and cut-off low activities. Some part of ozone may subside in the troposphere directly by the Hadley circulation or the Brewer Dobson circulation. Another source is production from photochemical rea...

Topic: Atmosphere Chemistry Pollution has always been an emotive irrespective of whether it occurs in the air, on land or at sea. In the latter half of this century much attention has been drawn to air pollution caused by modern methods of communication, although some cradles of the Industrial Revolution must have experienced local levels of high pollution quite unimaginable by present standards. Campaigns against the more widespread effects of atmospheric pollution are constantly mounted by the...

We are living in the midst of a great chemical experiment, and some serious consequences are becoming apparent to scientists. More than two billion pounds of chemicals are spewed into the air each year. These chemicals are brewing a disastrous stew, resulting in an atmosphere crisis. The greatest consequences of the atmosphere crisis may be the greenhouse effect (global warming) and the ozone deletion. If humankind wants to survive well into the next millennium, than we must stop this horrid des...

The Greenhouse Effect The earth's climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the build up of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide. Energy from the sun drives the earth's weather and climate, and heats the earth's surface. This causes the earth to radiate the energy back into space. Atmospheric greenhouse gases (water vapour, carbon dioxide, and other gases) trap some of the outgoing en...

INTRODUCTION In the beginning man lived simply and harmoniously with earth. However, as time progressed mankind's thirst for knowledge and more economical ways of doing things led to technological advances. These advances, in turn, led to the industrial revolution, the invention of the automobile, and growth of the automobile industry. Though making life on earth more comfortable, these industries and inventions emitted harmful gases into the earth's atmosphere. Damage to the earth's ozone layer...

... an ecosystem a variety of species would be affected. Furthermore, the same oxygen recycled by phytoplankton is breathed by all animals and man himself thus adding to the importance of the threatened oceanic food chain. A weakened ozone umbrella could also have a tremendous impact on wildlife. Moreover, in support of devastating impact on the crops and animals, a diminished ozone layer has been associated with environmental damage and concern. The potential effect on the earth's climate syste...

Triatomic oxygen, O 3, is most commonly known as ozone. It has a resonance structure, and can be drawn in two different ways: O = O- O-O = O It is a bluish, explosive gas at room temperature, and has a boiling point of -119? C. It has a melting point of -193? C, and is a blue liquid. It's critical temperature and pressure are -12.1? C and 53.8 atm, respectively. It has a pleasant odor in concentrations of less than 2 ppm, and is irritating and injurious in higher concentrations. The density of o...

Ozone, pronounced OH Z ohn, is a form of oxygen that is present in the earth's atmosphere in small amounts. Ozone in the upper atmosphere is a major factor in making life on earth possible. But ozone in the lower atmosphere contributes to air pollution. Ozone is used commercially in water purification process and as a bleaching agent. Ordinary oxygen molecules have two oxygen atoms, ozone has three. Ozone is produced naturally through photochemical and electric discharge reactions. Photochemical...

Man and the Ozone Ozone is perhaps one of the singularly most important molecules there is. No, not because man came from ozone, but because it forms a protective layer above the earth in it's stratosphere which allowed for the growth of life upon land. Before we had an ozone layer, the rays of the sun struck the earth unimpeded, barraging it with the deadly ultraviolet radiation which prohibited any chance of life on earth. However, there was life in the oceans, plant life in particular. This p...

Ozone Layer Thinning Caused By CFC's The ozone layer. What really is the ozone layer, and what does it do Is it just a plastic covering over the earth Why do we depend on the ozone layer so much for the earth's survival Without the ozone layer there would not be life on this earth. It protects us from all the bad UV ray from the sun, so we do not get skin cancer and die. It also keeps in the heat so we would not freeze to death. Also it lets in the sunlight heat in. That is why the ozone layer i...

Ozone Depletion And its Consequences The life on Earth is protected from harmful radiations by ozone layer. However, this shield is being damaged day by day due to harmful human activities. This paper will emphasize on how destruction of the ozone has and can further result in dire consequences to life on Earth unless steps are taken to reduce and eradicate this situation by covering the following vital points: + Introduction to Ozone layer. + Causes of depletion. + Effects of depletion. + World...

Weather satellites make it possible for meteorologists to closely watch our atmosphere and its weather. One of the more frightening findings over the last several decades is that the ozone layer in our upper atmosphere appears to be getting thinner. Scientists believe that the thinning ozone is due to certain chemicals that our society is producing. Chemicals know as chlorofluorocarbons (or CFC's for short) are used in air conditioners, refrigerators, styrofoam packaging, and insulation. For man...

Global Warming By A deel Salman The numbers are striking! No region of the world will be unaffected if Global Warming continues to increasingly grow. The issue is extremely interesting, scary and a bit of a shock as to how much we have abused and taken advantage of this Earth. First of all, it is important to know that the "greenhouse effect" is not a bad thing in itself. In fact, this planet would be a life-less waste land without its natural green housing. There are a collection of gases calle...
